    The percent yield of this reaction is 84.8 % (option A is correct)

    Explanation:

    Step 1: Data given

    The student isolated 15.6 grams of the product = the actual yield

    She calculated the reaction should have produced 18.4 grams of product = the theoretical yield = 18.4 grams

    Step 2: Calculate the percent yield

    Percent yield = (actual yield / theoretical yield) * 100 %

    Percent yield = (15.6 grams / 18.4 grams) * 100 %

    Percent yield = 84.8 %

    The percent yield of this reaction is 84.8 % (option A is correct)
